Although I lacked the foresight to find deals of my own last year, I am prepared to take advantage of the opportunity this year. 

Is that true for all banks or is this just with Navy Federal Credit Union? 

Be prepared for a longer vacancy.

It really depends on the risk vs. reward for you and how much time/money you have on hand.My gut reaction: lawyer up and prepare to sue both the city and land owner for creating hazardous living conditions.

I've been preparing myself and I'm now looking to build on my rental portfolio with the purchase of a two-flat, then more to follow.  

I will provide a packet as I would a bank to show my income and credit which is very very strong.  

Hi @Tyson Thomas to piggyback on @Mike Day's comment, definitely reach out to all of the banks in your surrounding area (large, medium, small, credit unions, etc.).

I have a savings sub-account at my credit union where I park leftovers for house stuff.

Report to a credit agency?

Speaking and shadowing that individual can help you avoid certain costly mistakes and better prepare you for your REI journey.
